Obtaining the Details About a Training Job

Sample Code

In ModelArts notebook, you do not need to enter authentication parameters for session authentication. For details about session authentication of other development environments, see Session Authentication.

  • Method 1: Use the specified job_id.
    from modelarts.session import Session
    from modelarts.estimatorV2 import Estimator
    session = Session()
    estimator = Estimator(session=session, job_id="618222c4-dc2f-4cfe-bc49-72b075b7552f")
    job_info = estimator.get_job_info()
    print(job_info)
  • Method 2: Use the training job created in Creating a Training Job.
    job_info = job_instance.get_job_info()
    print(job_info)
